Not far into Araújo you have to choose between two possible routes, but the option is not entirely obvious. The split is not far past the Iglesia de San Pedro (see photo), at a small square with an enclosed cruceiro and a bust of Dr. Eugenio Pinto Franco.
The two options are Maia or Moreira (preferred).
For Maia: The road turns Right here and descends towards the river. Here there is a quite dangerous crossing for the N13. It is my opinion that this should not be an option for pilgrims as it is quite clear that pedestrians are not meant to cross the N13 at this point. Doing so requires you to climb over the highway divider and to time the traffic well, taking note that the traffic coming from your right is going downhill and quite fast. The arrows will then take you back uphill to the church at Maia, and back down once more.
For Moreira: Keep on straight. The development becomes less intrusive, and the arrows lead you all the way to Moreira.
These two routes meet again in the Zona Industrial of Maia and are of equal length: 4.9km
